or the like directly from a standard lubricant x container (as for example a 25 pound or 50 pound 9 Claims. (Cl. 222-'-256) to apparatu for container) to a lubricant-receiving nippleor fitting or the like.

An object of the present invention is to provide new and improved apparatus for dispensing lubricant or other viscous fluid or semi-fluid.

Another object of the present invention is to provide apparatus for delivering lubricant or the like directly from a standard dispensing container' (as for example a 25 pound or 50 pound container) to alubricant-receiving nipple or fitting or the like. Still another object of the present invention is to provide a novel dispensing attachment adapted for detachable connection to 'standard lubricant-dispensing containers or the like which will withdraw lubricant in predetermined amount and which will thereafter deliver small charges of the withdrawn lubricant or. the like under high pressure to a lubricantreceiving nipple 0r fitting or the like. A further object of the present invention is to provide a simple and inexpensive dispensing attachment adapted for detachable connection to lubricantdispensing containers or the like-which will deliver lubricant or the like, at suitable pressure,

V directly to lubricant-receiving nipples or fittings or the like without the need for employing conventional refillable grease-guns and, which, at the same time permits more easy handling of the lubricant container or. the like.

Other objects and advantages of the present invention are apparent in the following detailed description, appended claims and accompanying drawings. Y

It has been customary in the past, to provide lubricant or the like instandard dispensing containers .(of 25pound or 50 pound or other suitable capacity) from which conventional greaseguns can be filled: the grease-guns being manually operable thereafter to deliver the lubricant, under pressure, to lubricant-receiving nipples or .fitti'ngs or the like. Various types of these standhave heretofore been employed with conventional grease-guns have been time-consuming and have greatly added to the effort required in lubricating tractorsautomobiles, trucks and other similar equipment. It has been suggested in the past to supply a lubricating unit having larger grease capacity than the conventional small grease-gun. These larger units have, however, not proven satisfactory since they are relatively expensive and cumbersome and since the process of filling them from standard grease containers has been a long. unpleasant and unsatisfactory operation.

Accordingly, the present invention contemplates the provision of a dispensing unit, of simple and inexpensive construction, which is adapted for quick attachable and detachable connection to a standard grease container orthe like and which will withdraw a predetermined amount of grease from the container and will deliver it through a flexible hose or the like, under relatively low pressure, to a grease-gun head; the grease-gun head being manually operable to deliver small charges of grease. under high pressure, to a grease coupler adapted for quick attachable and detachable connection to a conventional grease,- receiving nipple or fitting orthelike. The present invention further contemplatesthe provision of means forming part of the dispensing unit, wherebv the d spensin container can be quickly and easily picked up and carried to ans, convenient point.

For the purpose of illustrating the invention, there are shown in the accompanying drawings forms thereof which are at present preferred, although it is to be understood that the various instrumentalities of whichtheinvention consists can be variously arranged and organized and that the invention is not limited to the precise arrangements and organizations of the instru- .tion.

a. peripheral bead .32. is tor-med at the .upper end of the container 20; the edges of the body .21. and theiilid 2] being icrimped together after The discharge opening 26 also includes a circular base plate 39 having a generally tubular crimping flange 4i] drawn therefrom; the flange fitting within the boss opening 34 and defining an elongated opening 4|. The diameter of the base plate 39 is slightly greater than that of the boss 33 and is such as to fit within the inner clear diameter of the ring 35 with just sufficient clearance. to permit rotation "of the ring thereabout; the flange -31 of the ring 35 fitting over the periphery of the base plate 39 and anchoring the ring 35 thereto. The base plate 39 is secured to lithe-boss -33 by spot-welding the two together at suitable points as shown at 42. Instead of spotwelding, rivetser other suitable attachable means maybe used toseeure the base plate to the boss.

It is apparentthat the has plate 39 is immovablyftastened to the boss 33 of the body 2| while the ring 35 is rotatably mounted upon the base plate.

A central'apertured rotatable diso 4.3 is pivotally secured to the base plate 39: by .a flanged sheet metalpivotmember 44 which extends with.- intheeentralapertureof the. disc '23 and is spot- Weldedto-the base plate .39 as atl-fi. .I'he rotatable disc: 43. is also. provided with an elongated off-center port-hole 46 of generally the same shapeas. the opening .41. defined by the crimping flange Ail. VA notch '41 is provided at the perliphery of the disc. 4.3andis adapted to receive the inwardly-extending Ikeying. lug .38. formed onthe ring .35lso. that rotation of the ring .35 will also .causerotationoflthedise 43.

A thin annular sealing. gasket 89 is provided hetweenithebaseplate 3 9 andithe disc 43. .An ,arcua'te slot 511 is, provided on the disc 43 generally diametrically opposite the port. hole-4,6,; the molten being. adapted to receive a stop 5! pro- 'j'ec'ting. outwardly from the base plate .39. The slot. 49. and "the stop 5! .to serve. tolimit the rotation of theldisc 43 relative to the base plate 39; the openings '48 and l-i'being in full registration when thestop 51 is adjacent the left hand end wall'of the. slot .50 andbeing wholly out of registration when the stop is adjacentthe'right hand end wall ';of,' the slot '50.

A sealing gasket 52 is disposed within the ring 35 outside of the rotatable disc. 43.

When the dispensing unit to be hereinafter described in detail is .screw-threadedly connected within the, ring 35,, .the last. portion of the right hand locking rotation will produce frictional engagement with the gasket 52 and the disc 43 theicontainer isfilled toiorm the bead .32,.and

with any other quick attachment locking means "(a s vtor example a bayonet catch) to receive complementar'y locking means provided 'on the dispensing attachment.

The ring 35i's formed with an iii-turned annular flange 31-a t one-end. At'a'point spaced from the 31, an inwardly "projecting lug 38is pro- 7 and will cause clockwise movement of the disc 43 to bring the port hole 46 .into registration 'withithe opening 45 so as to'permit lubricant to fiowfrom the conduit 25, through the aligned openings 'dfi' and 4|, and into the'dispensing. unit. When the dispensing vunit is removed, the'first portion. of the left: hand. opening rotation will "the *disc 4,3 counter-clockwise to move the -'port hole 46 out of registration'with the porthole "81 thereby automatically to close off the dischargeopening 2E-and toprevent loss of lubricant 1 from the container 20.

If desired, the outer surface of the ring 3.5 may-beknurled or provided with-slight ribs (not shown) to permit .manual xgripping of the ring in order-to facilitate. locking and. unlockingirota- .tion' of thedisc 43.

"While I' prefer to employ the novel dispensing unit of the present invention with a dispensing "bontainer 'having'the automatic discharge opening described-above, it may be used with other -typesoif containers (including those disclosed in "my patents'enumerated hereinabove) to on the outer side of the end .wallLlfl. wall leais also provided with a plurality of cirwhich the dispensing unit can be connected in fluid- .tight relationship.

In the embodiment of Figures 1 to the dispensing unit includes a generally cylindrical member 53, having a reduced neck 54 at one end and having a transversely extending annular flange 55 at its other end; the flange 551,-being adapted to fit snugly within the ring 35"of the container 26. "L

.A gasket 56 and a collar or gland nut...i. 1 are disposed about the member 53 behind theig'flange 55; the collar or nut 51 being externallyl'screwthreaded as at 58 for detachable connection within the ring 35. The collar 51 may be provided with a hexagonal portion 59 whereby ,iti can be gripped by? any suitable tightening tool. ;Instead of being made hexagonal, portion 59 on the collar .51 may be knurled or otherwise formed to permit its being tightened and untightened by hand or -by any suitable tool.

A generally cylindrical opening 66 is provided in the side wall of the member 53 and an internally screw-threaded socket 6| is fastened to .themembje'r 53 in line with the opening 69, by

welding or brazing or any other suitable means.

The axis of the socket 6| extends generally at right angles to the axis of the member '53 so that, when the member 53 is fastened within the dis- 'the clockwise rotation will cause frici tional engagement'with the gasket 56, the flan e 55, the

gasket 52.and the disc 43 to move the openings .46 and 4| into alignment so as to permit flow of lubricant from the conduit into the member 53. Conversely, the first part of the counterclockwise unlocking rotation of the collar or gland .nut 51 will move the openings 46 and 4| out of alignment to close the discharge opening 26.

The member 53 is provided with inlet and outlet .check valves 62 and 63 respectively"... The inlet .check valve 62 may include a fiangedJcup-shaped body 64 fitted inside the left hand end of the "cylindrical member 53; the flange of the body 64 extending outside of the member;53 and providing the flange 55 described hereinabove. The

inner wall. 65 of the body 64 is centrally apertured fixedly to receive a headed pin 66on which a valve disc 61 is slidably mounted on the inner side of the wall 65. The wall 65 is also provided 'with a plurality of circumferentially. spaced valve ports 68'which are opened to permit flow of .lu'bricant'.Jtherethrough when the disc is moved to its innermost position away from the wall 65 as shown; in Figure 4 and which arefclosed when 'thediscofi'l is moved to outermost position against (the wall 65 as shown in Figure 5. I

The outlet check valve 63 includesa cup-shaped body 69' disposed adjacent the right hand end thereof and having a centrally apertured end wall .19 wherein the headed pin 1| of avalve disc 12 is slidably mounted; the disc 12 being disposed The end cumfer'ntially spaced valve ports' .13 which are adaptedto be closed when the disc 12' is in its -innermost position against the Wall 19 and which are adapted to be opened when the disc 12 is in its outermost position away from the wall 10.

The socket 6| is adapted detachably to receive the screw -threaded end of a cylinder -14forming- 6 part of a low-pressure hand pump; a' sealing gasket 15 providing a fluid-tight seal therebetween. 1

Slidably disposed within the cylinder 14 is a piston indicated generally by the reference character 16 which includes a shaft 11 which carries, at its inner end, a pair of oppositely-disposed cup washers or gaskets 18 of leather or any other suitable material held between metal washers 19. The shaft 11 of the piston 16 extends upward beyond the end of the cylinder 14 and through a centrally apertured cover which is screwthreadedly connected at the upper end of the cylinder 14. A handle 8| is provided at the upper 4 outer end of the shaft 11 while a helical spring 82 is disposed within the upper part of the-cylinder 14 intermediate the cover 80 and the upper metal washer 19; the spring 82 urging the piston 16 downward within the cylinder 14.

When the novel dispensing unit of the present invention is connected to the container 29, the cylinder 14 extends in generally vertical position spaced somewhat apart from the Wall of the body 2|.

A carrying handle 83 is connected adjacent the upper end of the cylinder l by means of an adj ustablestrap 84 passing around said cylinder and held tightly thereabout by a fastening bolt 85.

The carrying handle 83 is also adapted rigidly to be connected to the bead 32 of the container 29 by means of a lower curved shoulder or jaw 86 (adapted to fit beneath the bead 32), an upper shoulder or jaw 81, and a bolt 89 screw-threadedly mounted in the shoulder 81 and adapted to be screwed downward therein so as to grip the upper portion of the bead 32.

The handle 33 is also provided with a hose clamp 89 adapted to hold a delivery hose (to be hereinafter described) when the unit is not being used. The hose clamp 89 includes a generally semi-circular yoke 96 having a slight projection or lip 9| formed at its outer end and also includes a locking collar 92 which is pivotally connected adjacent the top of the yoke as at 93 and which is adapted releasably to engage with the projection 9| in the manner shown in Figure 9 so as to lock the hose within the yoke 99.

An elongated flexible delivery hose 94 has one end fitted about the reduced neck 54 of the cylindricalmember 53. An apertured connector 95 is fitted to the other end of the delivery hose 9s and isscrew-threadedly connected within the intake conduit 96 of a high-pressure or booster grease pump 91. A reduced opening 98 connects the inner end of the intake conduit 96 with the high pressure cylinder 99.

A piston IE0 is adapted for reciprocation within the cylinder 99; a fluid-tight seal being prois pivotally mounted-to the outside of the body of the pump 91 as at I08.

When a downward manual pressure is exerted adjacent the free end of the lever handle I94, the mechanical advantage provided by the pivotation causes the piston lot! to exert extremely high pressure (several thousand pounds per square nemas 1 i 0.82 leading from the bottom of the cylinder: 99

and provided with a check valve which includes achec-khall ;I I8 'andla helical spring 'I-II.

A relativelywshort. length. of flexible delivery hose I I2 is connected to thepump 9-1 :by an-aper tured coupling. .-I I3.- screw threadedly engaged within the outlet conduit Iii-l. The. hose [I2 is preferably thicker-Walled than the hose 94 to enable it withstanding the extremely .high pres- :SEHGS of lubricant fiorced. through it.- by the high pressure pump 91;.

Aquickattachahl'e :and detachable coupler :I I4 is connected to the other "endzoi the high. pressure hose H12. vTillie coupler :I'Hl may be any one of thezmany different types of couplers conventionally employed inlubricating systems. For example; the coupler H4 may be a multi-jawed hydraulic snap-on coupler (such as those shown in my U; S. Patents 2,274,753, 1,311,977 and 2,314,374) which isadapted for quick attachable and detachable connection to a conventional .apertured lubricant-receiving n-ippl'e-orifi'tting, I I 5 having a generally rounded convex head I Iii, an undercut shoulder II'l below the head, and a check ball H8 urged to closed position by a helical spring I-IQ, as shown in Figures 1 and 11.

Theoperation of the novel lubricant dispensing unit of the present invention will .now be described.

Assuming that 'the fol-lower plate '29 has been released. and. assuming that .the- .cylindricallmemher 53 has been connected to the discharge opening 25 of the container ,Zii in the .manner described above so as to open said .discharge opening, the piston "58 of the low pressure pump :is raised by manually pulling up on its handle BI.

The suction thus created opens 'the inlet check valve 62 and closes the outlet'check valve-63 and sucks lubricant from the container, through the conduit- 25, and the member 53 up into the cylinder M.

After the piston 16 has been raised to its. uppermost position, it is pushed (downward to close the inlet check valve 82 and open the outlet check valve 63 and to force the lubricant from the cylinder '14 into the .hose 94.

This raising and lowering of the piston It is repeated several times until sufiicientgrease has been. pumped. into the hose .94 to fillitand to. fill Lthejintake conduit 96 of the high pressure pump 91..

When this occurs, the piston isle'ft in the partially elevated position shownin Figure 1' wherein the coil spring 82 maintains a constant pressure uponiithe grease within the cylinder 14 tendto drive the grease into "the intake conduit 96;

After-the coupler I I4 has been connected to a nipple IE5 (which communicates with a bearing or'other part requiring lubrication), the lever handle IE4 is raised to its uppermost position as shown in solid lines in Figure 1 which lifts the piston IfiEi to uncover the opening 98 andto permit lubricant to be delivered therethroughfrom the intake conduit- $6 to the cylinder 89.

I Downward movement of "the lever handle I04 drives the piston I00 to the bottom of the cylinder &3 and thereby delivers thelubricant', under high pressure, past the check ball H0 and into the highpressure hose 1 I2.

When the lever handle wIIHI is agairr raisedlannthencharge of. lubricant will :be delivered .to

the cylinder--39 under, pressure of the springB-Z in the low vpressure pump and, upon. \downwamd movement of the lever handle, thisanew rchargeiof lubricant also :be delivered to: the highv pres- ;sure vhose II;2.

:This up-andrdown movement of the lever handle I 04 repeated several times until the high pressure hose. I;I Z-i's filled. with lubricant.

Thereafter; each np-and-down movement of the lever handle will deliver lubricant, under high pressurewthrough the coupler Inland into theapertured-Lnipple I;:I:,5- from which it. passes past -the .checlcihalr I :I 'B :to the :bearing. (not shown) or other part tov be lubricated.

- When the rfi-rst bearing has received sufii'cient lubricant, theacoupler 1:114:15 simply snapped ofi the. nipple ;I.'I 5 and attached to the next nipple or fitting II 5, and: :so on.

When the-lubricant within the-cylinder TM is depleted, dueto continued lubrication 1 of various bearings, etc., the handle BI is againraisedto its uppermost position. to refill the cylinder- 1 .4 so that lubrication'canzbe continued in the manner 'hereinabove described After all the lubricant-receiving nipples in 20113 vicinityhave been serviced, the hose 194 .(or the hose H2.) is inserted within the yoke Bil-10f. the hose clamp- '89 and is :lockedfinto position by closing the lock or collar 92 whereupon the entire unit ('namelythe container, the low pressure pump and "the high pressure pump) is: lifted by manually grasping the carrying handle 83 and-is carried to :a place forxservicing lofpad- 'ditional. lubricantqecei ving; nipples .It is apparent that the onlyoperations neces- :sary to effect lubrication or -ma-ny different bearings, etc. is the operation of the lever'hand le I04 and the occasional raisingof the piston handle 81 That is, no refilling. operations whatever are requ red .until the :grease container is wholly emptied. I

After the grease container has been emptied, the dispensing unitis disconnected therefrom "by unscrewing the: b"o1t 88 and the collar or gland nut 51 whereupon the container is discarded and the dispensing unit is connected to a new full container for further use.

Where the low-pressure pump assembly-oi" the present invention is used with 1av container having an automatic valve discharge opening as described above, itzmay be preferable to first loosen the bolt (and. the bolt Bit) before connecting .or idisconnectingithe' collartl so that the carrying handle 83v 'canibe swungout of' the way in order not to interfere with the locking and unlocking rotation of: the member 53 and. the cylinder 1'4.

1 "The handle 83 may be inexpensively formed fromysheet metal orzthe likefby simple andwel-lknown stampingand' forming'operations:

The boosterpunap :91 serves .as azshut-off {or the delivery hose-9'4. That. is, if the piston I200 is-left: in itsrlowermosltxpcsit'ron, after the greasing operation has' been completed, it will close oiT the opening 98 and will prevent the escape .of grease (which is always under pressure of the spring .82)

In. Figure '1 11 there is shown adirect push-type highpressure or booster pump I121) which :may be used-in place of the booster pump 19.1.

Ihe pump I.'2 flaincl-udes an intake conduit.- 5124 to which the aperturedconnector-Bf: :oi the :dclivery hose 94 is adapted to be detachably connected; The conduit I-2l communicates with a .highpressure-"cylinder- I22 through a reduced cne ile 1: g s

9 V A piston plunger I24 is adapted for reciprocation within the cylinder I22; a fluid-tight seal being provided at the upper end of the cylinder by an apertured gasket I25 and an apertured gland nut I26 (which is slotted as at I21 to receive a screw driver or other suitable tool) screw-threadedly connected within the lower end of, an enlarged cylindrical opening I28 extending above and in axial alignment with the cylinder As shown in Figure 11, the piston plunger I24 extends upward beyond the upper end of the cylinder I22 and through the gasket I25 and gland nut I26; its upper end being screwthreadedly connected to an operating shaft I29. The shaft I29 is provided with a lowermost enlarged flange I30 slidably mounted .within the cylindrical opening I28. The body of the shaft I29 extends upward through an apertured collar l3I-screw-threadedly mounted at the upper end of the pump I20 above the opening I28; a handle I 32 being provided at the outer end of the shaft I29.

A helical spring I33 is disposed within the opening I28 intermediate the flange I30 and the gland nut I26; the spring I33 normally urging the shaft I29 and the piston plunger upwardly to the position shown in Figure 11.

- A sealing cap or nose-piece I34 is screw threadedly connected at, the lower end of the pump I20; a check ball I35 being normally urged to closedposition at the lower end of the cylinder I2Z..by a helical spring I36 seated against the nose-piece I34.

In operation, lubricant is delivered from the hose 94 through the intake conduit 96 and the opening 98 and into the cylinder I22 in the manner described hereinabove.

The pump I20 is then forced against a fitting or nipple I I5 and the handle I32 is shoved-downward whereupon the piston plunger I24 drives the lubricant at extremely high pressure past the ;check ball I35 and into the fitting II5. When the handle IE2 is released, the spring I33 returns the piston plunger I24 to the uppermost position shown in Figure ll whereupon additional grease is forced into the cylinder I22 from the hose 94, the intake conduit HI and the openns I23.

, The handle I32 is then again pushed downward to send another charge of the lubricant into the fitting II5. This procedure is repeated until suflicient lubricant has been delivered to the fitting whereupon the pump I20 is moved to ;the next nipple or fitting to be lubricated.

The novel dispensing unit of the present invention issimple and inexpensive to manufacture and can be sold for aslittle as a few dollars complete. Thus, the low pressure pump, the carrying handle-and the member 53 can be constructed of relativelylight weight sheet metal 01" the like by simple operations well'known in the art. The high pressure pump can be of cast steel or the like and can be completed by simple conventional machining operations such as are Well known and commonly employed in the art.

The carrying handle 83 can be adjusted .to different-size containers by simply looseningthe bolt.85 and sliding the strap 84 along the outofsaid spring, said booster pump being adapted 10! side of the cylinder I4 to the proper height for connection to the bead 32.

Where the container is not provided with anupper bead sufliciently large to take the carrying handle 8|, the handle may be provided with. a suitable adjustable strap (not shown) similar,-

ing means may be provided for attaching thehandle M to thegrease container.

..As; used in the appended claims, the term refers. to a 25.. pound or 50v pound or other size container where-l; A in. grease or other lubricant or the like is com-: monly sold; and which is provided with a de-. livery or'ldischarge opening in its side wall (diseposed. near thebottom of the container with its standard grease container axis. either generallyhorizontal or upwardly inan-ordinary grease-gun or the like.
